Our stay (my girlfriend is from BKK, I´m German) was realy beautiful, we enjoyed a lot the location, the apartment on 20th floor with balcony for breakfast, dinner and happy hour.
We stayed 4 weeks, the size is spacious enough for 2 adults, we did half of the time cooking "at home" and rest in various restaurants of various types nearby (as it is the Japanese zone, lots of Japanese), local and Italian (good one just around the corner).
On 18th floor you find spacious gym and nice pool, both never crowded.
Communication with host was easy and fast.
We realy can recommend this place, was difficult to leave after 4 weeks....
